The NATO chief has expressed skepticism about the european union's ability to defend itself without us help, suggesting that the region would need to spend heavily to build its own nuclear weapons capability. The chief's comments were dismissive of the idea, with some outlets reporting the use of phrases such as "keep on dreaming" and "good luck" to convey the sentiment. The comments have reportedly sparked a backlash, with some criticizing the chief's stance on europe's security independence goals.
